CAR-5000 Appliance Is Optimised For Xeon Processor

Portwell Technology has announced the CAR-5000 network appliance, optimised for the quad-core Intel Xeon processor C5500 series paired with the Intel 3420 chipset. This communication appliance provides high CPU computing performance and boosts I/O throughput with an integrated PCI Express 2.0 solution.

Portwell's CAR-5000 server-grade network appliance features a 2U rack-mount chassis, dual sockets for the Intel Xeon processors - with an integrated PCI Express 2.0 and memory controller, high-speed Intel Quickpath Interconnect technology between the two processors, as well as Intel Turbo Boost, virtualisation and hyper-threading technologies - and the associated Intel 3420 chipset to meet high-performance computing requirements with up to 32 PCI Express 2.0 lanes and 12 PCI Express 1.0 lanes.

12 DDR3 memory DIMMs support up to 96GB system memory. The CAR-5000 two-socket, 2U rack network appliance provides maximum performance while supplying a variety of Ethernet interfaces and Ethernet ports, helping reduce energy and deployment costs. The high concentration of computing power and redundancy makes the CAR-5000 suitable for high-performance networking applications, such as UTM, IPS, IDS, anti-virus, firewall, VPN and content filtering.

Power Switches Are Optimised For USB Protection

Diodes Incorporated has introduced 0.5A single-channel power switches optimised for USB-port protection and other 3-5V hot-swap interconnects. The AP2145 (active low enable) and AP2155 (active high enable) provide complete protection solutions for consumer, computing and communication applications subject to the possibility of heavy capacitive loads and short circuits. The power switches are fully compliant with USB standards and are available in industry-standard SOP-8L and exposed-pad MSOP-8L-EP packages.

Their 10us transient response time prevents unnecessary system shutdown or restart, while their accurate 1A current limiting capability helps reduce system rail current requirements and related component costs. Offering reverse current blocking, over-current, over-temperature and short-circuit protection, as well as controlled rise time and under-voltage lockout, the AP21X5 parts are said to significantly improve the robustness of USB ports.

In addition, an inbuilt 7ms deglitch period on the flag output will prevent erroneous over-current reporting, without the need for any external components. UL and IEC60950-1CB scheme certified, the power switches are said to meet industry's most rigorous safety standards. Operating temperature rating is -40 to 85C and current consumption in shutdown mode is a maximum of 1uA.
